“In digestion there are 4 major organs that are involved in digestion process. This entails the stomach, small intestines, liver and the pancreas.
The pancreas is quite high up in your abdomen. It lies across your body where your ribs meet at the bottom of your breastbone, just behind your stomach. It is about 6 inches (15 centimetres) long and shaped like a leaf. The pancreas has 3 parts the head, body and tail.
The pancreas is a large gland that makes digestive juices and hormones, including insulin. The digestive juices flow down a tube (pancreatic duct) into the duodenum. The duodenum is the first part of the small bowel and is joined to the stomach.
Another tube (duct) joins the duodenum. The bile duct comes down from the gallbladder and liver and joins the duodenum right next to the pancreatic duct. The place where the two ducts join and meet the bowel is called the ampulla of Vater.”
